Hi,
Using a spektrum and a white noise sample i don't hear or see that result - in a short test.
I do hear and see a generel difference in volume on my meter. The rehersal sample seem to be around 4 db louder than the loaded sample, even if they according to the settings should be the same. I can't tell why, and i consider the voĉume difference to be a bug, as it's not an exspected behavior.
Do you exsperience the same result, if you balance the volumes and play the loaded samples root note in Pigments?
Am i missing something?
